Hi,
Thanks for the reply.
I'm using
OntModel omodel =
ModelFactory.createOntologyModel(PelletReasonerFactory.THE_SPEC);
OntModel bmodel =ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM)
to create the ontologies models that I want.
In this case I need to do this
omodel.read("file:/..ontology A");
bmodel.read("file:/..ontology A");
right ? Or can I get the basic model from "omodel" without creating the
"bmodel" ?
Thanks for answering my not so smart questions. :)
